Dawn Redwood needles curling a bit

[keithl]

Just noticed a few needles starting to curl a bit on my forest, is this something to be concerned about? Dont see any sign of bugs and trees are all otherwise looking healthy and growing well. We have had a few warmer days recently, but nothing crazy hot where I would expect some potential curling.

When plant leaves curl down, they're usually trying to limit evaporation.
When they curl up, they are evaporating a lot, sometimes to compensate for heat.

Did it change in the past two weeks? If so, please let us know!

Still looks pretty much the same. Maybe slightly less curled? I did repot this year and that tree is at the edge of the forest, so perhaps it got more root pruning that the rest, unsure. Everything is still growing well though, so seems like its not really a major concern.
